Abstract: Sleeve molding apparatus and methods for making multi-layer injection molded plastic articles in successive mold cavities.    In a first molding step, an inner sleeve is molded on a core in a first mold cavity, which may comprise a full body length sleeve or only a partial sleeve, such as an upper neck finish portion, The sleeve and core are withdrawn from the first mold cavity while the sleeve is still warm, and transferred without substantial de-lay to a second mold cavity for injection molding an outer layer which bonds to the inner sleeve. By transferring the sleeve at an elevated temperature into the second mold cavity, an improved bond is formed between the inner sleeve and outer layer which resists separation during a later reheat stretch blow molding step, and/or in use of the resulting article. In a preferred embodiment, a pasteurizable beer container is provided having a finish-only sleeve of a PEN polymer. In a second embodiment, a returnable and refillable water container is provided having a full-length body sleeve of a PEN  polymer. A multi-station injection molding apparatus is provided having a transfer mechanism, such as a rotatable turret or reciprocating shuttle, for cast-effective manufacture of preforms simultaneously in multiple cavity sets.

IPC: H03M7/30

Abstract: We present a method and apparatus for performing adaptive data compression. An alphabet and vocabulary in the encoder and decoder is built adaptively and stored in a dictionary as symbols are to be encoded and decoded. Each time an unknown symbol is to be encoded by the encoder, the encoder adds the symbol to the dictionary and transmits it in plain in the encoded string. The code words transmitted by the encoder include symbols and indexes. The state of a prefix bit preceding the code word indicates whether the code word is a plain symbol or an index of a symbol or string of symbols stored in the dictionary. The decoder examines the prefix bit of each code word as it is received to determine if the code word stores a symbol in plain or in index. If the code word stores a symbol in plain, the decoder learns the symbol by adding a sequence of symbols resulting from the concatenation of previously decoded symbols and the first symbol of the currently decoded symbol and by adding the symbol to its dictionary. If the code word stores an index, the decoder decodes the code word by extracting the symbol or sequence of symbols stored in the dictionary at the respective index in the dictionary.

Abstract: L'invention concerne des procédés et des dispositifs perfectionnés pour la détection et l'identification dans un échantillon d'une ou de plusieurs molécules cibles se liant en molécules sondes, en particulier en molécules sondes d'acide nucléique. Le procédé perfectionné consiste à mettre l'échantillon en contact avec une surface couverte d'un ou de plusieurs gradients de molécules sondes, en particulier de l'acide nucléique ou de molécules sondes analogues à l'acide nucléique, ces molécules servant à lier des molécules cibles dans l'échantillon, notamment des acides nucléiques ayant des séquences complémentaires ou partiellement complémentaires à une ou plusieurs molécules sondes. Un gradient sonde généré sur la surface est créé par la variation d'une propriété fonctionnelle, structurelle ou physique des sondes sur la surface. Le gradient est généré par modification, par ex., de la densité des molécules sondes liées à la surface, de la longueur de séquence sonde, de la séquence sonde, du type de séquence sonde, de la structure d'orientation des sondes, de la concentration de marqueur associé aux sondes. La détermination de l'emplacement, la vitesse et/ou l'étendue de l'hybridation d'un acide nucléique sur une telle surface de gradient sont utiles pour identifier les molécules cibles liées aux sondes et/ou pour mesurer la quantité d'une cible dans un échantillon. L'hybridation de molécules cibles avec un gradient de sonde d'acide nucléique peut être examinée comme une fonction des conditions de temps et/ou d'hybridation (par ex., température, concentration de sel, etc.). Les procédés et des dispositifs selon l'invention mettent en oeuvre des surfaces de gradient pour se lier à une ou plusieurs molécules cibles, en particulier des acides nucléiques (ou des séquences cibles) dans un échantillon, en détectant leur présence dans l'échantillon et en quantifiant la ou les cibles de ce type dans un échantillon.

Title: Device for a non-hermetic seal
Inventor: BEICHL STEFAN
IPC: F16J15/3288
Filed: 2002-04-16
Abstract: An arrangement for a non-hermetic seal between a stator and a rotor of a turbomachine in the root region of guide blades belonging to the stator, comprising a brush sealing ring which is mounted on the guide blades via a spoke centering means and whose bristles together with a rotating sealing surface form a fluid barrier which is permeable in a defined manner.     On the sealing side of lower pressure, a supporting ring for the bristles is arranged at a slight distance from the rotating sealing surface, and this supporting ring is integrally connected to the guide blade roots and can be segmented by means of parting seams.   The spoke centering means is designed to be permeable to pressure, as a result of which the brush sealing ring is pressure-relieved axially, with the exception of the bristle area between sealing surface and supporting ring.

Abstract: A roll-up curtain assembly includes plural, vertically spaced, horizontal roll- up rods extending across an opening. Each roll-up rod is coupled to a respective flexible curtain section and an electric motor. Actuation of the electric motor in a first direction of rotation causes rotation of the roll-up rod in a first direction for rolling the flexible curtain section onto the rod and moving the curtain assembly to the retracted, or open, position. Actuation of the electric motor in a second, opposed direction of rotation lowers the roll-up rod resulting in an unwinding of the curtain section from the rod allowing the curtain assembly to assume the extended, or closed, position. Plural vertically spaced curtain sections each having a respective motor/roll-up rod combination are coupled together and move upward or downward in unison.

Abstract: Apparatus and methods for covertly determining the rate of motion between a pixel-based imaging device and a target being viewed by the pixel-based imaging device. The method involves using the pixel-based imaging device to acquire a first and a second digital image of the target. The second digital image is acquired a time interval after the first digital image. The time interval and pixel counts for the pixel set within the first and the second digital image representing a particular portion of the target are then used to determine a rate of relative motion between the pixel-based imaging device and the target. Advantageously, the rate of relative motion is determined covertly such that the locations of the pixel-based imaging device and the target are not disclosed or broadcast to third parties.
